The Essence Demon Sect belonged to Zhenyuan Temple, and this matter was revealed by Han Muye while he was suppressing Zhan Tianming in the Yunteng Wasteland.
The major sects unexpectedly supported a sect with an ambiguous allegiance in the Yunteng Wasteland
This matter didn't harm Zhenyuan Temple's reputation, but it tarnished the name of the orthodox sects in the Daoist community for many years.
Among the sects that valued strength above all else, this matter was no secret, and no one cared.
However, there were plenty of private jokes, especially among low-level cultivators, which further damaged the reputation.
Han Muye knew that it was possible for them to come and intercept him because of this matter.
Fortunately, Zhenyuan Sect's Golden Immortal had left a thousand years ago, weakening Essence Demon Sect's strength considerably; otherwise, he would have had a hard time dealing with a Golden Immortal.
